EXERCISE ROCKING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 337,934, dated March 16, 1886.

Application filed January 14, 1896.

To all whom, it 11mg concern:

Be it known that I, GEORGE WAsHING- TON DEAN, a citizen of the United States, residing at the city and county of New York,in the State of New York, have invented new and useful Improvements in Exercise Rocking- Chairs, of which the following is a specification.

I make the rockingchair with its ease and comfort to the sick also a jolting-chair for producing healthful exercise similar to that of horse-riding, whereby an easy rocking movement is combined with a jolting action by means of the gentle exertion of the feet and limbs upon the floor. The momentum of the rocking movement of the chair and its occupant is the force which also produces the j olting exercise, and this latter movement is such as to be in, harmony with the rocking movement. For this purpose I combine with the long rockers a supplementary short rocker having an arc of greatly less radius than that of the long rockers, located about the middle of the length of the long rockers upon their rocking surface, whereby in the rocking movement of the chair the rockers proper are caused to be suddenly lifted from the floor and as suddenly let down upon the floor both in the backward and forward movements,giving two jolting actions to the occupant, while the feet are free from pressure upon the floor, affording comfort and exercise without straining the body.

The drawings show a rocking-chair having its rocker supplemented by short rockers, Figure 1 being a perspective view; Fig. 2, the long and short rockers; Fig. 3, the short rocker-bar in one piece,illustrating the jolting exercise; and Fig. 4, a rocker, showing the jolting fixed projection integral therewith.

The supplemental short rockers a, I prefer to make of a half-round wooden bar about two inches in diameter, so as to give a surface ra- SerialNo. 188,562. (No model.)

dius of about one inch and of a length sufficient to be secured crosswise on the under side of the long rockers at a point about the middle ot their length. This supplemental rocker-bar gives a good cross-bearing by its curved surface and prevents injury to the carpet; but each rocker may be supplemented by an independent short rocker of the form in crosssection described when the rocking-chair is mounted upon a platform.

The supplemental short rockers may be removably attached; but however applied they must be in line across the long rockers and must be arranged so that the chair will carry and rest upon them when unoccupied.

The supplemental short rockers may be wider or narrower than that stated, but they must be of semicircularform or oval to produce a short jolting-rocker upon the surface of a long rocker.

It is obvious my improvement can be used with a rocking-horse or other article mounted on rockers, and that the long and the short rockers may be made in one piece.

I claim 1. A rocking-chair having each of its rockers provided with a fixed projection on its lower side at about the middle of their length in coincident crosswise relation, whereby to produce combined rocking and jolting movements, as described.

2. The combination, with a rockingchair,

of a cross-rocker bar attached to the lower sides of its rockers at about the middle of their length, whereby to produce a j olting interruption of the rocking movement, as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
